Testing Static Random Access Memories


Book Description

Testing Static Random Access Memories covers testing of one of the important semiconductor memories types; it addresses testing of static random access memories (SRAMs), both single-port and multi-port. It contributes to the technical acknowledge needed by those involved in memory testing, engineers and researchers. The book begins with outlining the most popular SRAMs architectures. Then, the description of realistic fault models, based on defect injection and SPICE simulation, are introduced. Thereafter, high quality and low cost test patterns, as well as test strategies for single-port, two-port and any p-port SRAMs are presented, together with some preliminary test results showing the importance of the new tests in reducing DPM level. The impact of the port restrictions (e.g., read-only ports) on the fault models, tests, and test strategies is also discussed. Features: -Fault primitive based analysis of memory faults, -A complete framework of and classification memory faults, -A systematic way to develop optimal and high quality memory test algorithms, -A systematic way to develop test patterns for any multi-port SRAM, -Challenges and trends in embedded memory testing.




High Performance Memory Testing


Book Description

Are memory applications more critical than they have been in the past? Yes, but even more critical is the number of designs and the sheer number of bits on each design. It is assured that catastrophes, which were avoided in the past because memories were small, will easily occur if the design and test engineers do not do their jobs very carefully. High Performance Memory Testing: Design Principles, Fault Modeling and Self Test is based on the author's 20 years of experience in memory design, memory reliability development and memory self test. High Performance Memory Testing: Design Principles, Fault Modeling and Self Test is written for the professional and the researcher to help them understand the memories that are being tested.




Advanced Test Methods for SRAMs


Book Description

Modern electronics depend on nanoscaled technologies that present new challenges in terms of testing and diagnostics. Memories are particularly prone to defects since they exploit the technology limits to get the highest density. This book is an invaluable guide to the testing and diagnostics of the latest generation of SRAM, one of the most widely applied types of memory. Classical methods for testing memory are designed to handle the so-called "static faults," but these test solutions are not sufficient for faults that are emerging in the latest Very Deep Sub-Micron (VDSM) technologies. These new fault models, referred to as "dynamic faults", are not covered by classical test solutions and require the dedicated test sequences presented in this book.

Encyclopedia of Microcomputers


Book Description

"The Encyclopedia of Microcomputers serves as the ideal companion reference to the popular Encyclopedia of Computer Science and Technology. Now in its 10th year of publication, this timely reference work details the broad spectrum of microcomputer technology, including microcomputer history; explains and illustrates the use of microcomputers throughout academe, business, government, and society in general; and assesses the future impact of this rapidly changing technology."




Defect-Oriented Testing for Nano-Metric CMOS VLSI Circuits


Book Description

The 2nd edition of defect oriented testing has been extensively updated. New chapters on Functional, Parametric Defect Models and Inductive fault Analysis and Yield Engineering have been added to provide a link between defect sources and yield. The chapter on RAM testing has been updated with focus on parametric and SRAM stability testing. Similarly, newer material has been incorporated in digital fault modeling and analog testing chapters. The strength of Defect Oriented Testing for nano-Metric CMOS VLSIs lies in its industrial relevance.







ISTFA 2019: Proceedings of the 45th International Symposium for Testing and Failure Analysis


Book Description

The theme for the 2019 conference is Novel Computing Architectures. Papers will include discussions on the advent of Artificial Intelligence and the promise of quantum computing that are driving disruptive computing architectures; Neuromorphic chip designs on one hand, and Quantum Bits on the other, still in R&D, will introduce new computing circuitry and memory elements, novel materials, and different test methodologies. These novel computing architectures will require further innovation which is best achieved through a collaborative Failure Analysis community composed of chip manufacturers, tool vendors, and universities.




Defect Oriented Testing for CMOS Analog and Digital Circuits


Book Description

Defect oriented testing is expected to play a significant role in coming generations of technology. Smaller feature sizes and larger die sizes will make ICs more sensitive to defects that can not be modeled by traditional fault modeling approaches. Furthermore, with increased level of integration, an IC may contain diverse building blocks. Such blocks include, digital logic, PLAs, volatile and non-volatile memories, and analog interfaces. For such diverse building blocks, traditional fault modeling and test approaches will become increasingly inadequate. Defect oriented testing methods have come a long way from a mere interesting academic exercise to a hard industrial reality. Many factors have contributed to its industrial acceptance. Traditional approaches of testing modern integrated circuits (ICs) have been found to be inadequate in terms of quality and economics of test. In a globally competitive semiconductor market place, overall product quality and economics have become very important objectives. In addition, electronic systems are becoming increasingly complex and demand components of highest possible quality. Testing, in general and, defect oriented testing, in particular, help in realizing these objectives. Defect Oriented Testing for CMOS Analog and Digital Circuits is the first book to provide a complete overview of the subject. It is essential reading for all design and test professionals as well as researchers and students working in the field. `A strength of this book is its breadth. Types of designs considered include analog and digital circuits, programmable logic arrays, and memories. Having a fault model does not automatically provide a test. Sometimes, design for testability hardware is necessary. Many design for testability ideas, supported by experimental evidence, are included.' ... from the Foreword by Vishwani D. Agrawal




Testability Concepts for Digital ICs


Book Description

Preface Testing Integrated Circuits for manufacturing defects includes four basic disciplines. First of all an understanding of the origin and behaviour of defects. Secondly, knowledge of IC design and IC design styles. Thirdly, knowledge of how to create a test program for an IC which is targeted on detecting these defects, and finally, understanding of the hardware, Automatic Test Equipment, to run the test on. All four items have to be treated, managed, and to a great extent integrated before the term 'IC quality' gets a certain meaning and a test a certain measurable value. The contents of this book reflects our activities on testability concepts for complex digital ICs as performed at Philips Research Laboratories in Eindhoven, The Netherlands. Based on the statements above, we have worked along a long term plan, which was based on four pillars. 1. The definition of a test methodology suitable for 'future' IC design styles, 2. capable of handling improved defect models, 3. supported by software tools, and 4. providing an easy link to Automatic Test Equipment. The reasoning we have followed was continuously focused on IC qUality. Quality expressed in terms of the ability of delivering a customer a device with no residual manufacturing defects. Bad devices should not escape a test. The basis of IC quality is a thorough understanding of defects and defect models.
